With Prime Music, Prime members have unlimited, ad-free access to over a million songs at no additional cost to their membership. Prime members can choose exactly which songs and albums to listen to, or they can sit back and listen to hundreds of expert-programmed Prime Playlists. Prime members can also download songs from the Prime Music catalog to their mobile devices for offline playback on planes, trains and anywhere they’re without an internet connection.

“When Prime launched nine years ago, the program offered Free Two-Day Shipping on one million items. Today, that selection has grown to over 20 million items. Prime Instant Video now offers unlimited streaming of more than 40,000 movies and TV episodes, up from 5,000 at launch three years ago. And the Kindle Owners’ Lending Library now features more than half a million books to borrow for free,” said Jeff Bezos, Amazon founder and CEO. “Today we’re introducing Prime Music—more than a million songs from some of music’s best artists, plus hundreds of expert-programmed Prime Playlists, all at no additional cost. Prime Music is the latest great addition for Prime members and we think they’re going to love it.”

Early speculation was that Amazon would only make songs older than six months available as part of any service. However, USA Today points out, "Amazon says there is no such specific time window restriction, though it is unlikely members will have free access to the freshest material. Moreover, while Sony Music and Warner Music are active participants, there is a major holdout on the content side. Amazon has not struck a deal with Universal Music."

Customers can also download the latest Amazon Music app in the Android and iOS app stores.
